Question

#9 calculate the area of the colored shape: 9cm 6cm 4cm 7cm #1 42 in² #2 78 yd² #3 38 m² #4 79 yd² #5 66 ft² #6 87 yd² #7 11 ft² #8 20 m² #9 #10 190 yd²

Explanation:

Step1: Find area of outer rectangle

$A_{outer} = 9 \times 6 = 54$ $\text{cm}^2$

Step2: Find area of inner rectangle

$A_{inner} = 7 \times 4 = 28$ $\text{cm}^2$

Step3: Subtract inner from outer area

$A_{colored} = 54 - 28$

Answer:

$26$ $\text{cm}^2$
